Glow, a startup focused on helping enterprises secure corporate environments as AI adoption accelerates, has emerged from stealth with $180 million in funding.

The Series A round valued the company at $1.2 billion, making Glow one of the youngest cybersecurity unicorns and underscoring how aggressively investors are backing startups that promise AI-native protection for the enterprise. Glow is based in Tel Aviv and Palo Alto and was founded by Roi Tiger, a former Facebook vice president of engineering. The company describes itself as an endpoint security specialist.

Tiger said Glow is seeking to address security challenges facing enterprises as the use of AI on corporate devices increases. According to Verizon research, regular use of AI on corporate devices has risen sharply over the past year.

That increase has meant employees at many companies are now using bots, assistants, and agents to carry out increasingly complex tasks. At the same time, Glow says security teams are facing mounting difficulties as they try to keep pace with the rapid development and deployment of AI tools.

The company argues that existing security tools are not suited to the new risks. Glow says enterprises need a new security operating model that also uses AI, with a focus on preventing problems before they occur rather than responding after incidents happen.

“Prevention was always the right answer in security. It just never worked at enterprise scale without blocking the business,” Tiger said in a statement. “AI solves that. The moment we saw what AI made possible, we knew the endpoint could finally be protected the way it always should have been.”

Glow’s technology is built around specialized AI agents that continuously map an enterprise environment, assess potential risks in real time using context and reasoning, and make automated decisions. Those decisions can include determining which software should be allowed into a business environment and which software should be excluded.

According to the company, this approach is intended to reduce potential threats while avoiding unnecessary delays in employees’ work. Glow says the system operates in real time, allowing security decisions to be made without slowing business activity.

Glow attributes the speed of its agents to the fact that they run on Glow’s central servers rather than on endpoint devices. The company says this design prevents the devices themselves from becoming overloaded.

Although Glow has only recently come out of stealth, the company says it already has agreements with enterprise customers in the healthcare, retail, and financial services sectors. It has not disclosed the names of those customers or the number of deals.

Glow said it will use the new funding to accelerate deployment of its technology in the United States and to strengthen the team building the software at Glow Labs, the company’s research arm.

The funding round was led by Sequoia, Cyberstarts, Greenoaks, and Redpoint Ventures. Other participants included Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures.
